The kind of use case I see for getting the results of the match is if you have a date in a nice localised format: <date>11th January, 2002</date> and you wanted to convert this into an xs:date (2002-01-11). Now you could do that with a lot of fiddly string manipulation functions, but it would be a lot easier to create a regular expression: ([0-9]{2}) (\w+), ([0-9]{4}) and use the results of the subexpression matches to give you the date, month and year.
